Could someone tell me what might be the cause of a mercury vapor light to
intermittantly go off and in a few minutes come back on? It doesn't do it
consistantly, but rather often.

1. Bad lamp.
2. Bad ballast.
3. Bad wiring.
4. If solar activated, photodetector being fooled by stray light or
someone messing with it using a flashlight or laser pointer.
